Hi all members of Oracle,
I am having a weird issue with Solaris 11. I hope somebody could help me out.
I have installed Solariss 11.1 with Napp-it and created a zfs folder from mirrored pool (8 vdevs)

I am testing the ability to detect missing/failed HDDs and resilver time. However, the zfs status doesn't report any missing HDDs if I pull one of them out, but the command cfgadm -al know the device is missing.
Zfs Status won't report any problems until I actually run some scan command such as format, cfgadm...
The chassis and motherboard I'm using is Supermicro and they are Hot-pluggable.
2 months ago I have tested that functionality, the zfs works very well, it can detect and re-detect quickly. But i don't remember what OS it was ( I tested on OpenIndiana, Solaris 11.0, Solaris 11.1)

The above bug is that ZFS/FMA do not report a hot-remove operation. This means that your hot-plug
testing is hit by this bug but an actual failed disk will work as expected. See the example below.

I'm having trouble getting the right hardware set up today to provide an example of the correct
failed disk interaction but I included one below from October when another customer saw the same
failure with hot-remove testing.

SUNW-MSG-ID: ZFS-8000-LR, TYPE: Fault, VER: 1, SEVERITY: Major
EVENT-TIME: Mon Oct 22 15:20:41 MDT 2012
PLATFORM: ORCL,SPARC-T3-4, CSN: 1120BDRCCD, HOSTNAME: gibberfish
SOURCE: zfs-diagnosis, REV: 1.0
EVENT-ID: 9e8cc30b-5b4f-c055-ef30-9e349f8e764c
DESC: ZFS device 'id1,sd@n5000c500335e106b/a' in pool 'pond' failed to open.
AUTO-RESPONSE: An attempt will be made to activate a hot spare if available.
IMPACT: Fault tolerance of the pool may be compromised.
REC-ACTION: Use 'fmadm faulty' to provide a more detailed view of this event. Run 'zpool status -lx' for more information. Please refer to the associated reference document at http://support.oracle.com/msg/ZFS-8000-LR for the latest service procedures and policies regarding this diagnosis.

pool: pond
state: DEGRADED
status: One or more devices are unavailable in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or 'fmadm repaired', or replace the device
with 'zpool replace'.
Run 'zpool status -v' to see device specific details.
